WEEDING ATTACHMENT FOR CULTIVATOBS.

Specification of Letters Patent.

Patented Mar. 23, 1920.

Application filed November 25, 1918. Serial No. 264,092.

To all whom it may concern.-

Be it known that I, WALTER H. LONG, a citizen of the United States, residing at Poplar Bluff, in the county of Butler and State of Missouri, have invented certain new and useful Improvements in Weeding Attachments for Cultivators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in earth-working devices and more particularly to a weeder designed particularly for attachment to cultivators such as those used in working growing corn, the arrangement being such as to destroy all weeds simul taneously with the cultivating operation.

The object of the invention is to provide an extremely simple and inexpensive Weeding attachment which may be easily and cheaply manufactured and which may be quickly applied and adjusted to practically all types of wheeled cultivators.

With the foregoing object in view, the invention resides in the novel construction of the attachment as herein described and claimed.

Figure 1 of the accompanying drawings is a perspective view showing the invention attached to a cultivator standard.

Fig. 2 is an elevation of the attachment.

Fig. 3 is a transverse sectional view with part of the attaching shank in elevation.

Fig. 4 is a disassembled perspective view of the attachment.

In the drawings above briefly described, the numeral 1 designates a cylindrical cast metal shank disposed vertically and prvided on its lower end with a circular head 2 having a bolt-hole 3 and a series of teeth 1 around said opening. A clamp 5 is provided for attaching the shank 1 to a cultivator standard 6, said clamp consisting of two cast metal blocks 7 and a bolt 8 for drawing them together, one end of said blocks having seats 9 for the shank 1 while the other ends of said blocks are formed with similar seats 10 for the standard 6. By forming the clamp in this manner, it is adapted to numerous forms of cultivator standards and may be swung horizontally to the most appropriate position, as well as permitting turning adjustment of the shank 1.

An adjusting and coupling block 11 is provided with a horizontal bolt-hole 12 alined with the bolt-hole 3, and is also formed with teeth 13 meshing with the teeth 4. A bolt 14.- passes through the boltholes 3 and 12 for clamping the block 11 adjustably to the head 2. Below the bolthole 12 and transverse thereto, the block 11 18 provided with an additional opening 15, sald opening receiving a stud 16 formed lntegrally with one end of a weed-cutting blade 17. A nut 18 is threaded on the stud 1'6 to clamp said stud and the blade 17 against turning movement when in use, and 1t will be seen that this arrangement permits adjustment of the blade upon a longitudinal axis to obtain the best results.

The entire device may be easily and inexpensively manufactured and may thus be sold at a minimum price, and when applied will be highly efficient and in every way desirable. In fact, the device has been successfully used on the farm of the inventor, and has produced excellent results, destroymg all weeds simultaneously with the cultivating operation. Any suitable number of the attachments may be used and they may be adjusted as occasion may demand.

Since probably the best results are obtained from the details shown and described, they are preferably followed, but within the scope of the invention as claimed, numerous minor changes may well be made.

I claim In a weeding attachment, a straight horizontal blade having an integral stud projecting longitudinally from one end, a coupling block having upper and lower horizontal bores at right angles to each other, the lower bore receiving said stud, a nut threaded on said stud for clamping said blade against further rotation after proper adjustment, a straight cylindrical attaching shank having a head on its lower end contacting with one side of said block, a bolt passing through said upper bore and through said head for adjustably securing said block to said head, and a clamp for attaching said shank to a cultivator standard, said clamp having an eye in which said shank is secured for vertical and rotary adjustment.

In testimony whereof I have hereunto set In hand.

y WALTER I-I. LONG.
